CATTLE-GUARD- Specification of Letters Patent.

Patented Aug. '7, 1906.

Application filed September 28, 1905. Serial No. 280,508.

T aZZ whom it may concern:

Be it known that I, JACOB WV. WYATT, a citizen of the United States, residing at Magazine, in the county of Logan, State of Arkansas, have invented certain new and useful Improvements in Cattle-Guards and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cattle-guards.

One object is to provide a guard for association with railroad-tracks for the purpose of positively preventing the passage of cattle over the tracks from one field to another.

Another object of the invention resides in the provision of a cattle-guard of the nature stated embodying such characteristics that it will lie between and upon opposite sides of the tracks so as not to interfere with the passage of rolling-stock, but be so disposed as to provide a gate in the event that cattle at tempt to pass over the tracks from one field to another.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accomp anying drawings, and particularly p ointed out in the appended claims, it being under stood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a 'top plan view of my invention in its normal position between rolling-stock rails. Fig. 2 is a side elevation illustrating the gate in its vertical position. Fig. 3 is a detail view of the gate broken away to illustrate its frame. Fig. 4 is a similar view of the plate.

Referring now more particularly to the ac companying drawings, the reference characters 1 and 2 designate rolling-stock rails mounted u on the usual ties, as shown.

Mounte upon a tie 3 is a U-shaped bracket 4, whose legs 5 and 6 are directed upwardly, as at 7 and 8, respectively, each terminating in an eye 9 for the reception of a rock-shaft 10. Mounted upon this rock-shaft 10 is a gate comprising a solid piece of material 11, mounted upon a U-shaped frame 12, whose sides 13 and 14 pass beyond the respective ends of the rock-shaft 10 and are then bent inwardly, as at 15 and 16, respectively, for

engagement in the eyes 17 and 18 respectively, of the legs 19 and 20 of the wire frame 21, upon which latter is mounted a plate 22, for a purpose presently understood.

Mounted upon the tie 23 in any suitable manner is a crank-shaft 24, whose ends are directed upwardly, as at 25, each upwardlydirected end being then directed toward the aforesaid shaft 10 and each provided w1th an eye 26 for engagement with the bight portion 21 of the wire frame 21 of the plate 22.

By reason of the upwardly-directed portions of the shaft the plate is held normally above the ties, as is also the inner end of the gate; but it will also be understood that neither the plate nor the gate extends so far above the ties as to be arranged in a plane with the upper edges of the rails 1 and 2. It will thus be understood that rolling-stock may pass over the rails 1 and 2 without being interfered with by the cattle-guard or the cattle-guard with the rolling-stock; but owing to the peculiar mounting of the plate 22 and the gate and the association of the plate and gate together the gate-will be caused to move from a horizontal to a vertical plane in the event that the cattle should attempt to pass over the tracks from one field to another, for the reason that pressure by cattle upon the plate 22 would cause an immediate upward movement of the gate. Obviously when confronted by the gate an animal would be prompted to turn back, and as soon as 1t has left the plate 22 the gate will immediately fall to its horizontal position between the tracks by reason of the helical spring 27, connected to the bend 28 of the crank-shaft 24 and with the tie 29, as shown.

It is thought entirely unnecessary to illustrate in the accompanying drawings the guards employed for the sides of the tracks 1 and 2, for the reason that the guards for the sides of the track are precisely the same as the guard therebetween. guards between the tracks and upon the sides thereof may be used directly adjacent the guards herein described for the purpose of preventing cattle passing from one field to another in a direction opposite to the direction for the operation of the guard illustrated in the drawings. In other words, it is thought that the guard illustrated in the drawings will suffice to illustrate the invention.

What is claimed is 1. A cattle-guard comprising in combination a plate; a crank-shaft upon which said A duplicate set of plate is mounted at one end; a gate pivoted to the opposite end of said plate, said plate and gate being disposed between the rails of a railroad-track normally in horizontal position; a rock-shaft upon which said gate is mounted whereby said gate may be raised to a vertical position upon the application of downward pressure upon the plate; and a spring connected to said crank-shaft, for returning said parts to their normal position.

2. A cattle-guard comprising in combination a plate; a crank-shaft mounted for a rocking movement and connected to one end of said plate; eyes provided at the opposite end of said plate; a gate; hooks upon said gate and adapted tobe received on said eyes ;said gate and plate being disposed normally in horizontal position; a rock-shaft upon which said gate is mounted, adjacent to said hooks, whereby said gate will be raised to a vertical position upon the application of downward pressure upon said plate; and a spring connected to said crank-shaft to return said parts to their normal position.
